Detour Ahead in B

Detour Ahead in B

Key of B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to E (ascending perfect fourth), E to E (ascending unison), E to D# (descending half step), D# to C# (descending whole step), C# to C (descending half step), C to F# (ascending tritone), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to G (ascending minor third), G to B (ascending major third), B to B (ascending unison), B to G (descending major third), G to C (ascending perfect fourth), C to G# (descending major third), G# to F# (descending whole step), F# to B (ascending perfect fourth), B to F (ascending tritone), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to E (ascending half step), E to D# (descending half step), D# to D# (ascending unison), D# to F (ascending whole step), F to E (descending half step), E to E (ascending unison), E to F# (ascending whole step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F# to B by perfect fourth.

Scales for Improvisation

B major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
